How can bond energies be utilized to calculate the enthalpy change of a chemical reaction?
Bond energies can be used to calculate the enthalpy change of a chemical reaction by comparing the energy needed to break bonds in the reactants with the energy released when new bonds form in the products. The difference between these two values gives the overall enthalpy change of the reaction.

How do the enthalpy of reaction bond energies compare to the enthalpy of formation in chemical reactions?
In chemical reactions, the enthalpy of reaction is the total energy change during the reaction, while bond energies are the energy needed to break or form specific bonds. The enthalpy of formation is the energy change when one mole of a compound is formed from its elements in their standard states. The enthalpy of reaction is influenced by bond energies, but it may not always directly correlate with the enthalpy of formation.

What is the fomula of chemical energy?
Assuming chemical energy means the enthalpy change (measured in joules), there are several methods to calculate chemical energy, although there is no one 'formula'. The simplest way is to calculate the bond energies between the atoms in the molecules and subract the total initial energy from the total final energy. If bond energies aren't provided, more complex methods are required. If you're looking for the change in enthalpy in the reaction A --> D, and are given the changes in enthalpy for A --> B, B --> C, and C --> D, then adding the enthalpy changes for the given reactions will give you the desired enthalpy change.
